Vermiculite Fireproof Insulation Board - Brick Effect Vermiculite is a naturally occurring aluminium-magnesium silicate layer that expands with the application of heat. This expansion process is called exfoliation and the resulting material is used in bulk form or processed to boards by a press forming process. The board can be worked easily with wood working tools. It can be sawn, drilled and sanded. http://www.vitcas.com/vermiculite-fireproof-insulation-board-brick-effect
